We stayed in Los Gigantes, so named because of the giant cliffs. It's not the best for beaches although it didn't really matter in this case as the wind and conditions made the sea too dangerous for bathing. One day we took a trip to Playa de las Americas. It's a more touristy area - especially for Brits. An Irish pub on every corner and every restaurant offering full English breakfast, English sports and fish and chips.
The day we went there the weather was very mixed. Standing on the prom you could choose which weather you wanted.
These two photos were taken immediately after each other.
